This thing Vapes like a steam locomotive! The Kayfun IS one of the best RBA's out there these days. Highly recommend it for anyone. Even newbies can get amazing results easily if you can wrap some wire around a drill bit and string it with some cotton. Ultravaping.com mailed it SAME DAY! Awesome! (And I got a free t-shirt too!) Just too bad they use the US Postal service. They are NOT fast at all. I would recommend only using FedEx or UPS in the future. I paid more than going rate for this device, but ultravaping.com had it in stock. I just didnt think they would go cheap and use the post office. That's my only complaint. The Kayfun truly is amazing and worth the wait.
